Patent GB-2115114-A (GB)
Title: Hydraulic control valve
Inventor: LADANYI LASZLO
IPC: G05D16/06
Filed: 1983-02-14
Abstract: A compact control valve for regulating the pressure in a duct is provided. The flow of liquid from the duct into a by-pass passage 7 is controlled by a valve member 9 which is urged away from a valve seat 8 when the pressure in the duct is above a pre-set limit. The movement of the valve member 9 is controlled by a pressure- sensitive diaphragm 11 which is connected to the valve member 9 by a housing 12 containing a spring 13, whose tension is adjustable and which urges the valve member 9 against the valve seat. The pressure in a closed chamber above the diaphragm 11 is controllable. Thus, the pressure prevailing in the duct before the valve member will open is governed by (i) the relative areas of the diaphragm and the value seat, (ii) the pressure differential across the diaphragm and (iii) the tension in the spring, the latter two influences being adjustable to give the desired upper pressure limit in the duct. <IMAGE>

Title: Method for fabricating a semiconductor device
Inventor: KINSBRON ELIEZER
IPC: H01L21/225
Filed: 1983-02-24
Abstract: A method for forming a shallow and highly concentrated arsenic doped surface layer (20) in a silicon bulk region includes the steps of forming an arsenic doped polysilicon layer (11) in contact with a preselected area of a bulk region (14) surface in which the surface layer is to be formed and completely oxidizing the polysilicon layer at a rate exceeding the rate at which arsenic diffuses in the bulk region. Since arsenic has a relatively high silicon/silicon dioxide segregation coefficient and the oxidation rate exceeds the arsenic diffusion rate, arsenic accumulates at the silicon dioxide/silicon interface during oxidation, and nearly all of the arsenic in the region of the polysilicon layer above the preselected area is driven into the bulk region surface by the oxidation to form an impurity layer having a very high surface concentration of arsenic.

IPC: F01D5/18
Filed: 1983-06-24
Abstract: A pressurized fluid is vented via ports 15 from a cell 6 in a turbine blade 3 and the pressure of the fluid in the cell is inferred from the change in the heat dissipation of the probe as measured at 28 as a change of current flowing through the probe 18. This is used to check that the ports 15 are unobstructed. Means are provided for calibrating the apparatus so that the results obtained can be compared with those which would be expected. <IMAGE>

Title: Ignition system for an internal combustion engine
Inventor: SCHMIED HELMUT
IPC: F02P3/04
Filed: 1984-03-08
Abstract: The ignition system includes first and second threshold value switches (16, 17) whose inputs are connected to a common a.c. generator (22) and which render the contact breaker (8) conductive when they are switched on. The a.c. generator (22) supplies an a.c. voltage signal (Ua) whose peak preceding portion switches on the threshold value switches (16, 17) and whose peak following portion switches off the threshold value switches. The contact breaker (8) is normally blocked by the first threshold value switch (16) otherwise it is blocked by the second threshold value switch (17) and a timing circuit (32). A logic circuit (29) prevents interference pulses from initiating random ignition operations. Also, when the ignition system is carrying current and the engine is not in operation and the second threshold value switch (17) and the timing circuit (32) have switched off the contact breaker (8), the logic circuit maintains the contact breaker (8) non-conductive until the first threshold value switch (16) again blocks the contact breaker (8). <IMAGE>

Abstract: A power amplifier comprises an input amplifier circuit, and an output amplifier circuit including two series-connected complementary MOS transistors. One of said MOS transistors receives as a bias voltage the DC component of an output signal from said input amplifier circuit. The other MOS transistor receives a fixed bias voltage from a separate bias circuit. Both the MOS transistors receive the A.C. signal to be amplified from the input amplifier circuit. The bias voltages to the two transistors are set at the same small value, thereby maintaining the dynamic range, and at the same time, reducing quiescent power consumption. <IMAGE>

Title: Apparatus for hardness testing
Inventor: MEYER REINHART
IPC: G01N3/42
Filed: 1985-07-01
Abstract: A hard penetration member (2), applied to a testpiece (10) contacts a point on the testpiece (10), so that the depth of penetration of the member under a test force (weights, 19, 19', 19'') can be measured. A punch (1) to be subjected to the test force carries the penetration member (2) and is axially guided in a tube (5) which tube is axially guided in a mounting member (6) which can be raised and lowered relatively to the testpiece (10). A depth sensor (12) measures the relative displacement between the punch (1) and the tube (5). The tube (5) carries a sensing foot (30) having two contact points 11 which bear against the testpiece (10) in a common straight line with and on opposite sides of the point of application of the penetration member, while the sensing foot is mounted on the sensing foot tube rotatably about a horizontal line which intersects that straight line perpendicularly, at the penetration point. Springs 35 bias arcuate bearing surfaces 34 of fact 30 against rollers 9 in tube 5. The sensing foot (30) can therefore adapt to changes in inclination of the testpiece (10) without measurement errors in regard to the depth of penetration. <IMAGE>

IPC: B03B9/02
Filed: 1985-08-02
Abstract: In a method for beneficiating coal or kerogen-containing oil shale values by froth flotation, improved recoveries and improved grades of the organic mineral values are obtained by first treating the ores containing them in an attrition milling apparatus to liberate the organic values from associated inorganic impurities. Attrition milling also provides special surface characteristics to the liberated organic values rendering them specially adapted for beneficiation by fine particle flotation. In accordance with the process, liberation is achieved by attrition milling for a time sufficient to provide particles of from about 1 to about 10 microns.

Title: Apparatus for the discontinuous wrapping of sweets
Inventor: KMOCH WERNER
IPC: B65B11/30
Filed: 1985-09-24
Abstract: The invention relates to an apparatus for the discontinuous wrapping of sweets, employing a gripper wheel 1 which has a plurality of radial holding elements 2a, 2b and, disposed alongside it, a wrapping wheel 3 which has a corresponding number of holding elements 4a, 4b, and rotates in the same direction of rotation as the gripper wheel, a wrapper H being fed radially from outside into position between the opened holding elements of the gripper wheel. The object of the invention is to increase the output of discontinuously operating machines for hard- centre caramels. The problem on which the invention is based is that of so devising the transfer of sweets from the gripper wheel to the wrapping wheel that longer wrapping wheel stoppage times result. According to the invention, this is achieved by a transfer part 5 which takes the form of diametrically opposed arcuately outwardly pivoting pairs of forceps 5d which serve on every second indexing step of the gripper wheel to take over two partially wrapped sweets from the gripper wheel at stations IV and V and, upon double onwards movement of the wrapping wheel, simultaneously delivers the two partially wrapped sweets to two adjacent holding elements of the wrapper wheel. Folding of the wrapper into tube form is completed during transfer to and onward movement of the wrapper wheel, simultaneous end twisting of the wrappers of two sweets being effected during wrapper wheel dwell at stations VIIa and VIIb. <IMAGE>
